The rich fish stocks on Canada's west coast have been commercially exploited for a century and regulated by the Canadian government for many decades. The salmon, halibut, and roe herring fisheries are the most important, and the efforts to manage the stocks since the introduction of extended fisheries jurisdiction (EFJ) provide insights into the special requirements in managing migratory species (salmon) and fisheries, such as roe herring, that are dependent on export markets. Early efforts were based almost entirely on biologic considerations. Starting in the 1960s, limited entry programs were used in an attempt to reduce economic inefficiencies and to protect the stocks, but these failed because the economic incentives to remaining participants were unchanged. Landings taxes and trasferable quotas have been proposed as means of rationalizing these fisheries, but any scheme that fails to address the crucial links - biologic, economic, and internatonal - cannot succeed
